KNOWLES LOOM WORKS, OF WORCESTER, MASSACHUSETTS LINT CLEARERFOR FILLINGsror MOTIONS Application filed March 24, 1928. Serial No. 284,403.

This invention relates to improvementsin devices for insuring properoperation of filling stop motions by removing therefrom any lint whichmaycollect during the operation of the loom.

In certainfilling stop motions, particularly those on broad looms wherethe forkis located at the center of-the loo1n,-thelay is provided with awell or-depressioninto which the tines of the filling fork pass whenweft is absent. When weft is present the fork-is held up and isprevented from moving into the well at that point in the'beatup of thelay where indicationto stop because of weft failure may occur.Whenweaving with certain kinds of yarn itis found that lint collects inthe well and supports the fork, having the effect of permittingcontinuedoperation of the loom even though the weftbe absent, because ofthe fact that the fork is not permitted 'to drop into the well. It is animportant object-of my present invention to provide means for clearingthe well of such lint-as may collect and thereby insure proper operationof the stop motion. 7

One form of center filling stop motion which has gone into general useemploys .a fixed bracket extending rearwardly from the breast beam andhaving a cam face along which moves a portion of the stop motionmechanism which-ismounted on the lay. It is a further object of mypresent invention to mount a clearing device on the'lay to be moved backand forth with the latter and to derive its motion partly from structurecarried by the bracket.

In one forminy invention. employsa' hooked member which movesback andforth in the well of the filling stop motion in -a direction transverseof the lay so as to draw line forwardly. It is a furtherobjectof myinvention to associate with the hooked member retaining deviceslocatedin the well and operative to prevent movement of the lint to the rearpart of the well after it has been moved forwardly by the hooked member.

WVitlrthese-and other objects in view which will appear asthedescription proceeds, my invention resides in (the combination andarrangement of parts hereinafter described and set forth in the claims.1 V

In the accompanying drawings, wherein I have shown a convenientembodiment of my invention,

Fig. 1 is avertical section through a portion of the loom showing afilling stop motion having my invention applied thereto,

Fig. 3 is a detailed vertical section on line 33 of Fig. 2 showing themanner. of operating my invention, and j 'Fig. Al is a detailed verticalsection online Referring to the drawings, I have shown; i

a 100m frame 10 and a lay 11 tobe moved toward and from the frame eachbeat of the loom. Secured to the breastbeam 10 of the loom frame is abracket 12 havinga lever 13 pivoted thereto as at 14. By means of mech-I anism not shown the lever is held normally inthe position shown inFig; 1. An adjustable cam plate 15 is held by a bolt 16-to the bracketand is-so placed as to expose the up per rearendof the lever 13 asclearly shown in Fig. 1. I I i The lay is provided with a bracket 17'to'which is pivoted as at 18 a dagger carrier 19 which supports the dagger20. An upwardly extending link 21 pivotally connected at the lower endthereof to the carrier is attached at the upper end thereof to an arm 22ofarocking fork member 23. Said member is provided with tines 24 whichextendinto the well 25 in the'upper forward portion of the lay 11. Thelay may be provided with the usual race plate 26 and may have a backstay27 to position the reed 28.

'When the lay is in rear position the dagger 20 is held in raisedposition on the cam plate 15 and the effect of this is to raise thetines trainee 'MIASSACHUSETTS, A CORPORATION OF 24 to the dotted lineposition shown in to permit the dagger 20 to have direct engagementwiththe lever 13. Continued forward movement of the lay will thereaftereffect stoppage of the loom by mechanism not shown but set into actionby the rocking of lever 13 around the axis 14.

I have shown hereinonly sufficient structureto indicate the manner inwhich my invention may be used and portions of the filling stop motionhave been omitted for the sake of clearness. The matter thus fardescribed forms no part ofmy present invention and ma be of the usualconstruction, references being made-to Patents Nos. 560,036 to Hutchinsand 1,369,417 to Gagnon fora more complete disclosure of the structureand operation of the particular form of filling stop motion illustrated.

In carrying my present invention into effect Iqprovide means forclearing the well 25ofanylint which may accumulate therein. Accordingly,I provide a stud which ismounte'don bracket 17 to move with the lay andmount on said stud a lever 31 having an upwardly extended arm 32 locatedpreferably in front of thelay. To the upper end of said arm 32 I pivot aplurality of clearing members 33 the rear of each of which is'formedwith a hook 3 1. The members 33 lie below the member-24 so as not tointerfere with the operation of said member or the upright link 21.

The lever 31 is provided with a rearwardly extending arm 35 whichextends through an eye 36 formed as part of the bracket 12 as shown moreclearly in Fig. 4. The rear end of the arm 35 is weighted as at 37 ifdesired, although I may dispense with the weight in view of the factthat the end 35 extends through the closed eye 36 and is therefore givenpositive motions in opposite d1- rections.- i

The hooked'members 33 normally lie in thebottom of the well in theposition shown in full lines in Fig. 3 when the lay is in its rearwardposition, or in the position shown in dotted lines in Fig. 1. As the laymoves forwardly its position will change with respect to the eye member36 and the rearwardly extending arm' 35 of the lever 31 will be raisedrelatively to the stud 30 to produce aleft hand movement as viewed inFig. 1 on the part of lever 31 around its supporting stud. The effect ofthis is to move the upright arm 32 forwardly to move the hooks from theposition: shown in Fig. 3 to the position shown in full lines in Fig.1.Said hooks are therefore effective to carry forwardly any mass of lint-Lsuch as that indicated in Fig.3.

In order to retainthe lint or other accu-" tween and on the sides of thehooked members These peg members operate to prevent the lint from movingrearwardly when the hooked members 33 moveback into the well uponrearward movement of the lay.

Asshown in Fig. 3 there is an open space below the member 23 definedbythe ears l1 and 42 which afford pivotal support for said member 23 andare mountedon the lay. In this way there is provided a suitabledischarge opening at the forward endof the well 25 for removal of thelint.

Frointlie foregoing it will be seen that I haveprovided a very simpledevice which is movable back and forth in the well 25 to engage any lintor other accumulation which maycollect in said well. It will further beseen that the movement of the lint removing element is effected by theforwardand backward movement of the lay and that said hooked members arein forward position where they cannot interfere with theoperation of thefilling fork at. that time in the cycle of It will also be seen that the.peg members extending upwardly from, the bottom of the:

well act not only to retain the-lint but also because of the fact thattheyare .incllned forwardlyaid in the discharge of the lint the loomwhen the filling fork will move 'downwardly in its, normal operationFurthermore, itwill be noted. that the sup-. 1

23. is provided withan .opening which the lint may pass; v
